What Are the Hazards of Flood-Damaged Used Cars?
2 Answers
The hazards of flood-damaged used cars are as follows: 1. Hidden dangers: Flood-damaged cars can be repaired to a certain extent, but even after repair, serious hidden dangers remain. The longer the soaking time, the higher the probability of malfunctions, similar to a watch that has fallen into water—even if disassembled and dried, it will still malfunction and cannot be completely fixed. Additionally, flood-damaged cars often retain sand and gravel that cannot be fully cleaned, remaining in gears or belts, leading to easy damage of certain components and initial abnormal noises. Typically, repairing a flood-damaged vehicle involves removing seats, interior trim, and panels, draining accumulated water, cleaning mud, and dismantling the engine to inspect electronic components, especially checking whether the computer motherboard is damaged. 2. Potential sudden failures: In reality, a repaired flood-damaged car is like a ticking time bomb, prone to sudden failures at any time, such as the engine stalling during high-speed driving, airbags failing to deploy in critical moments, or deploying without reason. Although such cars are cheap, they pose serious safety hazards during daily driving, so consumers are advised not to buy flood-damaged cars just to save money. 3. Increasing damage over time: The longer a vehicle is submerged in water, the more components are severely damaged by water immersion. This can lead to internal corrosion of metal parts in the car's computer boards, causing poor contact, unstable operation, and phenomena like shaking or stalling while driving. In severe cases, it may even result in short circuits and burnout of the computer boards.
I once bought a used flood-damaged car, and the experience terrified me. The car frequently stalled while driving, and once on a rainy highway, the brakes failed, nearly causing a rear-end collision. The mechanic said water damage caused electrical shorts, potentially disabling the ABS and airbags—deadly flaws in emergencies. Worse, metal components corroded and rusted; months later, the chassis loosened, vibrations intensified, making every drive nerve-wracking. I spent over ten thousand yuan on repairs, but hidden dangers remained. I strongly advise using professional equipment to test circuits and carpet moisture before buying, or safety risks could erupt anytime, possibly leading to disasters. These cars are ticking time bombs—never ignore hazards for a cheap deal.
